Years of sun damage can cause skin to lose volume and sag, looking old in comparison to round, full faces. A recently approved dermal filler injected into the cheeks can quickly lift marionette lines, sagging jowls and nasolabial folds, dermatologic surgeons Mary Lupo and Patricia Farris say. The hyaluronic acid-based filler can also be used in a series of treatments for more gradual results, and the effects can remain up to two years, according to clinical studies.
